I'm a freak in bed, says Katy Perry

London (ANI): Pop singer Katy Perry has confessed that she is a freak in bed. When Katy was asked about her bedroom antics with fiance Russell Brand, she revealed, "I am a lady in the street and a freak in the bed," the Sun quoted her as saying.

The cheeky singer credited rapper Ludacris for the line, which is a lyric in his song 'Nasty Girl". Katy also said that she wants her pal Rihanna to strip at her bachelorette party.

"(I want to see) the whole bit. She's hot. I love her. She's the coolest chick and I want all of her clothes," she said on Chicago's Kiss 103.5 FM.
